Two very adorable mertoddlers who love to play, explore, and make new friends.
As the older of the two, Urchin always tries to make sure Rainbow doesn't get into any troublesome situation...although Rainbow insists she can take care of herself.
If you're ever swimming/diving in their underwater world and you encounter them, don't be surprised if they approach you and give you welcoming hugs. And it's best if you hug them both at the same time...If you only hug one of them, the other will get jealous.
